Shelly Pro 4PM

Wired this into my panel for a few lighting circuits and the DIN rail mount made the install way cleaner than I expected. Each channel’s power metering shows up separately in the app, which has been great for spotting which circuit is drawing too much.

The power metering per channel is spot on—I can finally see exactly what each circuit in my panel is pulling without guessing. Setup in the app took me under ten minutes, and the relay clicks are reassuringly solid.

The DIN rail mounting made installation in my panel box straightforward, and the four independent channels let me control separate circuits without extra hardware. Setup took me under ten minutes, and the metering per channel has already helped me spot which appliance drains the most.
